PORTABLE KILN ,PLATTINGL Application led February'ZS, 1927. Serial No. 171,599.

My present invention relates to the manufacture of brick and more particularly to lan improved portable kiln platting for use in building kilns.

In the manufacture of brick at the pres ent day, where the brick is built into a kiln either manually or by mechanical means, it is necessary to cover the top of the kiln with a layer of refractory material for the purpose of conservingl the heat. Also it has heretofore been necessary to cover the side walls of the kiln with refractory material but this has been obviated by the use of portable scoving described and claimed in a patent granted to me under No. 1,548,794 of August 4, 1925. rlhe use of the vplatting, however, is still necessary and in laying this platting, the entire top Vof the kiln is covered with brick, which is necessarily done at considerable expense. One or two layers of brick are generally placed on the fiat and comparatively close together, although in the early stages of the burning of the kiln, it is necessary to have the brick constituting the platting slightly separated in order to allow the steam to escape, and after the kiln is dried, these openings must be closed during the remainder of the burn. The cost of laying this platting adds considerably to the cost of the brick and my present invention is designed to overcome the objection of prior methods of procedure and with a view to reducing the cost of manufacture.

In carrying out my present invention,

therefore, I have provided a platting composed of relatively large slabs that are portable and may be moved from place to place and repeatedly used, and which slabs are provided with means for enabling them to be readily lifted and also provided with perforations for allowing thev escape of steam in the preliminary stages of the burn and which perforations may be readily closed by loose brick.

The principal object of my invention, therefore, is an improved method of forming a platting for kilns and the like.

Another object of my invention is an improved portable kiln platting.

Other objects and novel features of the construction and arrangement of parts comprising the device will appear as the description of the invention progresses.

`Referring to the drawings, 10 designates channels of any suitable n size and length, spaced apart from each other, and connected by angles 11, which angles are secured to the channels 10 by brackets 12. Passing through perforations in the channels 10 and spaced apart from each other, are reinforcing bars 13` of any suitable length and diameter. Secured to orassociated with each of the channels 10 and on opposing surfaces thereof, are members 14, which members have their upper surfaces lying in the same horizontal plane as the upper surface of the channels 10. Pivotally secured to the channels 10, adjacent the ends thereof and within the space defined by the members 14, are handles 15, such handles being normally housed within. the space defined by the member 14, as indicated in Fig. 4. The structure above described is associated with a mold, not shown, and refractory material 16-poured into the mold in and around the reinforcing bars 13, as indicated in Fig. 2, after which insulating material 17 is poured into the mold on top of the refractory material 16, such insulating material being brought to a level defined by the horizontal plane in which lies the upper surface of the channels 10. During the molding process, perforations 18 are formed in the composite slab composed of the materials 16 and 17, these perforations 18 being of any suitable diameter and of any suitable number.

The composite slab is of any suitable dimensions, as above explained, and the handles 15, being pivotally mounted, may be brought into the position shown in Figs. 1, 2 and 3, or folded downward into the position shown in Fig. 4. The slabs, while being of considerable weight, are yet relatively light and may of the platting relatively cool.

vices attached to a crane or other suitable lifting devices and by means of which they may be transported to any point desired.

When the kiln is built up, the heretofore expensive operation of building platting over the top thereof with one or two layers of brick, and with a space between the same for the escape of steam during the first portion of the burn, the platting, formed of the slabs above described, are placed in position on top of the kiln as close together as possible until the entire surface is covered. The burn, being started, the steam may escape through the perforations 18 and when the preliminary part of the burn is over, work'- men go over the top of the platting and place bricks on top of the various perforations 18, thus preventing egress of heated air from the interior of the kiln, and they are enabled to readilyv perform this operation for the reason that the insulating material 17 keeps the top By having the hinges 15 pivotally mounted and housed within the limits of the space defined by the member 14, I am able to stack up the slabs when not in use.

Having thus described my invention, what I claim as new is:

1. An improved portable kiln pl att-'ing comprislng a rectangular slab of refractory and insulating material, said slab being provided with a plurality of perforations kextending therethrough. Y

2. An improved portable kilnplatting comprising a rectangular slab of refractory and insulating material, said slab being provided with a plurality of perforations extending therethrough and with reinforcing` members embedded in the slab and extending transversely thereof.

8. An improved portable kiln platting comprising a slab of refractory and insulating material, said slab being provided with a plurality of perforations extending there-v through and with reinforcing members eX- tendinO` transversely and longitudinally thereof?.

4:.' An improved portable kiln platting comprising a slab comprised of refractory and insulating material, arranged on the bottom andv top faces thereof respectively, said slab p being provided with a plurality of perforations extending therethrough and with transverse reinforcing members embedded in the refractory' material and means accessible from the top face of the slab for lifting and transporting the slab. A

In test'nnony whereof, I'have signed my name to this specification.
